Creating a secure hash of a string using HMAC-SHA256

[frumpus]

I have no idea how to do that.

I am supposed to hash a string, along with a secret code (so i guess 2 strings) using the HMAC-SHA256 algorithm.


Any guidance on how to do this would appreciated.

I think this link will get you started:

http://msdn.microsoft.com/en-us/library/system.security.cryptography.hmacsha256.aspx

it shows how to do what you need with a file, you just need to adjust it to work with your string instead of a file. I'm pretty sure the "secret code" you mention is the same as the "Key" or "Secret Key" referred to in this article. That's the general concept of keyed cryptography.

I hope that helps. Let me know if you have any trouble getting the function on that MS page to do what you want.
